Hi Dan,
Version 1 is available here for FS2002, I wouldn't bother though - I warn you it is complete rubbish!
Can't see any reason why V3 wouldn't work in FS2002, the AFCAD/AI would be way out though.
Unfortunately I've lost my #1 FS2002 CD so I can't convert V3 for you.
Just noticed over at Avsim there is another version of bristol for FS2002 with filename: bia2003.zip Might be a better choise for you.
Birdman.
I tried V3 in FS2002 a long time ago. I seem to remember that it worked, but it was on the top of a "small hill" which shouldn't be there.
Apart from that it worked fine.
